Now you know what you can do if you come into some serious coin!--hate to estimate what its worth.
Beware that the cache is in full view of the house,creative stealth may be needed (flouro jacket de rigueur,maybe) Might pay to park further down the road close to mansion grand entrance & walk back. Cache should be an easy find,its the same colour as its surroundings,& its a small Eclipse tin--look for *V/V*
Cache contains log book & pencil.When replacing please place back firmly & in the right way up (arrows on cache) Any pics would be welcome.
